I’m noticing a strange performance issue with my website: Wildiferemovalpro

On Chrome and Safari, it loads perfectly fine. However, when I try to open it in Firefox, the loading spinner just keeps going, and the "Time to Interactive" feels significantly longer.

I’ve already tried:

Clearing my Firefox cache.

Disabling my extensions.

Checking on different machines.

Is anyone else seeing this? I suspect it might be a script or a specific CSS rendering issue unique to the Gecko engine. Would love it if someone could take a quick look and let me know if they see any red flags in the console.

I am having issues where pages I open will show it continuously opening (Page load status on tab keeps bouncing even when page is loaded) some page I need to try a couple times to load content. This seems to have started when I upgraded my Mac to OS 2.6. Currently I do not have any extensions or themes to troubleshoot. I did try in troubleshooting mode and everything worked fine, but all the documentation points to themes. I have tried clearing cache, quitting, restarting my computer it always comes back. Is there anything I can do to stop this otherwise all my work on Firefox will have to be moved elsewhere. Below the guess about my OS it says my OS is 10.15 which is incorrect it is Tahoe 26.3. I am not sure why this would come up as a 2019 OS.

Best,

Gina

Describe exactly what isn’t working (e.g., “Videos pause every 5 seconds on Firefox version 118.0.1”).

Include when and where it happens (e.g., which website, device, or operating system).

Mention any steps you’ve already tried (e.g., “I cleared my cache and restarted the browser, but the issue persists”).

Hi, on my macbookpro. Searches take minutes to load, websites take minutes to load. Youtube takes minutes to loand, but once loaded and I start a video, it runs for a couple of minutes then video suddenly stops and I have to wait for couple of minutes for the video to continue again and it keeps repeating, all my other web browsers (Safari, Chrome, etc..) works perfectly. It also uses sFirefox is bascially unusable! I am running the latest version.

I also saw a NoScript XSS Warning:

NoScript detected a potential Cross-Site Scripting attack

from https://www.youtube.com to https://accounts.google.com.

Suspicious data:

Error: Timeout! DOS attack attempt?,(URL) https://accounts.google.com/ServiceLogin?service=youtube&uilel=3&passive=true&continue=https://www.youtube.com/signin?action_handle_signin=true&app=desktop&hl=en&next=%2Fsignin_passive&feature=passive&hl=en

Long Delay occurs loading multiple websites, from facebook to other sites and I often get a delay of over 20 seconds with any site involving a CDN connection of various types. I am using W11, latest version of Firefox. 148.0 (Says latest version)

When it happens I can see the connection url in the bottom left hand corner includes a CDN part. Settings are Proxy settings "Use system proxy settings"

• DNS over HTTPS is set to "default protection"
• IPv6: ISP is has just changed from gigaclear fibre to toob fibre, but it has made no difference.
• Have cleared cache. No change

This is very frustrating. Started a couple of months ago. I have ended up using Chrome ratherthan Firefox and I am close to giving up with firefox. Help appreciated.

some times the Youtube video's won't load i thought that it's my network glitch but my network is good only in this browser the videos won't load sometimes and some website's like amazon also won't load some times it keeps on loading but nothing will be loaded . i need to restart the whole browser to make it work please fix it Zen browser .

Mozilla firefox browser is SOOOOOO SLOOWOWOWWWWW loading and working. Takes literally minutes after clicking open the browser for it to even finally eventually load the tabs - pages. Then it often lags, slows way down. Making it useless for people who value our time and life. 133.03 version. says its current up to date.

Please fix it so it works correctly efficiently.

Am not being hyperbole but I swear to God I love Firefox more than anything. Okay, let's get to the main topic. I have a problem with Firefox on my pc, whenever I open Firefox one of my CPU thread is dying and its causes brutally lags. I know I have a potato rig but at least fix this browser as smooth as before. After I having a problem with dying threads whenever I open a tab and going to a website I desire it took so long isgt. I thought my pc was the problem one and I think "Ah I should upgrade my pc, but I still in debt" and it turns out the Firefox was the main problem.

Please Firefox fix this for me, don't suffer me more. I'm migrating to Chrome for a while cuz the Chrome didn't kill my CPU thread (I tested it for almost 2 weeks).

I attached you images from time to time, hope you could understand it! ;)

Hi! I’ve noticed that the site with Slider Revolution installed opens quite slowly in my browser. Do you have any idea what this might be related to? In other browsers, it seems to load just fine. Thanks in advance for your help! Link: https://kasiinod-ee.ee/

Seems I've noticed an issue with playing of YouTube videos the last few days. It seems that either the video(s) is slower to load and/or is slower to play. While it's not terribly slower in human time it's slower than normal in computer time. I'm not having this problem in Chrome. Cookies and cache are cleaned multiple times a day. So, I'm a little stumped as to why I'm having this issue. Any comments would be appreciated. Thanks

Hi hi, I just did a complete reset to factory settings of my laptop (MSI), and a wipe of my hard drives too. After reinstalling Firefox (literally the first thing I did after setting up windows), it runs more slowly than before the reset (even for a basic search on Google/Duckduckgo). I am also unable to load any pages under the domain discussions.unity.com : the page loads forever, it's impossible to click on anything (even the hovering styles don't work), and I get a banner at the top of the screen that says "This page is slowing down Firefox. To speed up your browser, stop this page.". Also the memory usage for this page skyrockets (gone up to 4000MB??). I've disabled the 2 extensions I have (Dark Reader and Adblock Plus), restarted Firefox, restarted the computer, cleared the cache, even turned off the mozilla syncing, nothing worked. Any idea on what could be happening here? It's the first time in using Firefox for over 15 years that I've seen this happened.

Thank you for your time and attention <3
